fittin E BENEZER BLACKMAN, OF NORWALK, CONNEGTICUTP Letters Patent No. 92,695, dated July 20,1869

mnovamm' IN LAm-BURNERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom "it may concern Be it known that I, Ennnnznn Bnkckttnn, of the town of Norwalk, county of Fairfield, and State of Connecticut, have invented a new and useful Improvement in the Burners of Kerosene-Lamps; and I do hereby declare that the following is a full and correct description thereof, reference being had to the accompanying ment the wick-tube will be made aifltight, except at the bottom.

To enable others skilled in the art to make and use 7 my invention, I will proceed to describe the same.

In the drawing- Figure 1 is a plain view of the wick-tube and the lever.

Figure 2 a sectional view of the same.

In the first place I make the tube A of a length to reach nearly to the bottom of the lamp, with fine coriugations to the fiat parts running from top to bottom; this improves the free passage of the oil for combustion by the flameat the top.

The tube is fixed to the burner B,- without forming a chamber or recess for air, as is usually done. Airpeiforations are made, as usual, inside of the cone.

In the face of the tube I make two slots or ports, 0 D, to allow the pins of the plate E to, penetrate the wick, to work it up or down.

I form a thin plate, E, of metal, with the face that goes next to the tube covered with a thin piece of leather, or other suitable and equivalent niaterial, to

fit close to the tube, to make it air-tight over the slots,

and to slide up and down similar to a slide-valve.

This plate slides up and down by the action of the lever G, and has two sharp points passing through the lcather,'a.nd into the wick, through the slots in the tube.

The plate is kept up close to the tube by'the pressure cf the spring H on the shank of the lever, or other equivalent device.

The lever G is fastened wit-ha joint to the plate E,

and extends outward, as shown in the drawing, and

a linger-and-thumb piece on the end to operate with, for lowering or raising the wick, which is done by first pulling outwards to relieve the points from the wick, and then working up" or down; and when the wick is properly adjusted, the spring presses the plate close home to the tube and makes it air-tight, and the points penetrating the wick prevent its falling when the lamp receives a sudden jar. 1

The utility of this arrangement is in the additional security from explosion,'(\vhich is often caused by the escape of the oil or gas through the openings in the tube.) Also by the tube being made air-tight, the supply of oil for combustion will be improved and bum steadier. The corrugations will also allow the flow of the oil to be more 'free.

What I claim as my invention, and desire to secure by Letters Patent, isv The slid ng plate E, provided with a thin piece of leather, and the spring-lever G, when arranged to operate as herein described, and for the purpose set forth.
